The site for the Pentagon 9/11 Memorial lies immediately adjacent to the Pentagon where Flight 77 collided with the building. The design by Julie Beckman and Keith Kaseman was proposed as an open gravel plaza interspersed with trees and steel benches—as markers for each victim—oriented in the flight path of the downed plane. This night view of the memorial as completed in 2008 features steel benches cantilevered over shallow illuminated pools, each forming a memorial unit within the gravel field.
